As Donald Trump left a caucus site here, his campaign manager said that the precinct had run out of ballots.

“I think the state’s just bringing more,” Corey Lewandowski said shortly before 7 p.m. at Palo Verde High School. “That’s all I’ve heard so far. Big crowds, and waiting for more ballots to arrive.”

The concern came amid scattered reports of irregularities at Nevada caucus sites, including people voting more than once, overseers improperly wearing campaign paraphernalia and some failing to check voter IDs.

“They’re still counting the ballots so we don’t know the exact results, but I want to congratulate Donald Trump on a strong evening tonight and I want to congratulate the grass roots – the conservatives across this country who have come together behind this campaign,” Cruz told supporters at a YMCA in Las Vegas.

Donald Trump, flanked by his sons at a Las Vegas casino Tuesday evening, exuberantly declared victory in Nevada less than an hour after the caucuses closed, saying that his success would be good for the nation.

“Soon the country is going to start winning, winning, winning,” he said.

Trump thanked his volunteers and then predicted success in upcoming states, including Sen. Ted Cruz’s home state of Texas and Gov. John Kasich’s home state of Ohio.

Donald Trump won the Nevada Republican presidential caucuses on Tuesday, strengthening his bid for the party’s nomination after similarly decisive victories in the New Hampshire and South Carolina primaries.

The New York billionaire’s victory came a week before a dozen Super Tuesday contests that could move Trump closer to becoming the prohibitive favorite in the competition for party delegates.
